(ultrasonic element)

Multiple ultrasonic elements 3 are for example on bearing surface 1a along the longitudinal arrangement of strip shell 13.It is in addition, for example each Individual ultrasonic element 3 is respectively positioned between a pair of electrodes 5 (as another expression way, that is to say, that positioned at bearing surface 1a along width Spend the center in direction).Can suitably set multiple ultrasonic elements 3 quantity and interval etc., in the example in the figures relative to The balanced configuration of sensor 7 has 4 ultrasonic elements 3.

In order to increase the area to body surface conveying ultrasonic wave, ripple is disturbed also for utilizing, and multiple ultrasonic elements are set 3.But in description of the present embodiment, substantially only lay particular emphasis on the ultrasonic wave from each ultrasonic element 3.

The structure (including size) of multiple ultrasonic elements 3 is for example mutually the same；But it can also be mutually different knot Structure.In addition, the ultrasonic wave way of output (frequency and intensity (wave height) etc.) of multiple ultrasonic elements 3 can also may be used with mutually the same With different from each other.Example is given one example, such as between four ultrasonic elements 3, the frequency of ultrasonic wave is mutually the same.In addition, Center two ultrasonic elements 3 between, the intensity of ultrasonic wave is mutually the same, outside two ultrasonic elements 3 it Between, the intensity of ultrasonic wave is mutually the same.Two ultrasounds of the intensity of the ultrasonic wave of two ultrasonic elements 3 in center than outside The ultrasonic wave of ripple element 3 is stronger (e.g., from about 2 times).

Fig. 3 is the exploded perspective view of the ultrasonic element 3 from body surface side.Ultrasound from Fig. 4 is side opposite from body surface side The exploded perspective view of ripple element 3.Fig. 5 (a) is the sectional drawing of ultrasonic element 3 corresponding with Fig. 3 V-V lines.Fig. 5 (b) It is the schematic diagram for illustrating the convergence of sound.

Ultrasonic element 3 for example with：Generate the vibrating elements 35 of ultrasonic wave；(hreinafter referred to as " the lens of acoustic lens 37 37 "), it is located at body surface side relative to vibrating elements 35, and the ultrasonic wave convergence for generating vibrating elements 35；And lid 39, cover The body surface side of lid lens 37 simultaneously abuts with body surface.

(vibrating elements)

As shown in Fig. 5 (a), a pair of exciting 43 of vibrating elements 35 for example with piezoelectrics 41 and clamping piezoelectrics 41. In addition, being not particularly illustrated, a pair of exciting 43 is covered by insulating barrier (such as welding resistance).

Piezoelectrics 41 are for example clamped along polarised direction by a pair of exciting 43.Therefore, if to a pair of exciting 43 Apply alternating voltage, then the through-thickness of piezoelectrics 41 stretches.That is, piezoelectrics 41 vibrate.Also, by by alternating voltage Frequency (such as 20kHz more than) of the frequency as ultrasonic wave, ultrasonic wave is generated by the vibration of piezoelectrics 41.

Specific material, the shape and size of piezoelectrics 41 and exciting electrode 43 can suitably be set.For example, piezoelectrics 41 It is the tabular using polarised direction as thickness direction.The thickness of the plate is substantially fixed, and the flat shape of plate is, for example, circle.Pressure The material of electric body 41 can be monocrystal or polycrystal, and what can be enumerated as representational material is lead zirconate titanate (PZT).A pair of exciting 43 is made up of metal level, and the metal level is formed the one of piezoelectrics 41 with substantially fixed thickness To interarea (broadest surface of tabular) substantially in whole surface.

In addition, as described above, had been illustrated as vibrating elements 35 (vertical using the deformation of the polarised direction of piezoelectrics 41 To piezoelectric effect) situation.But vibrating elements 35 can also use other forms.For example, vibrating elements 35 can be single Chip type or twin lamella type, by limiting deformation of the piezoelectrics 41 along the direction vertical with polarised direction (thickness direction) (laterally Piezoelectric effect), so as to which through-thickness produces flexural deformation.

The alternating voltage applied to a pair of exciting 43 for example can be the intermediate polarity (relative of a pair of exciting 43 In the positive and negative of reference potential) voltage of alternating inversion, current potential on the basis of one of exciting electrode 43 can also be made, and only make The current potential of another exciting electrode 43 changes.The current potential of another exciting electrode 43 can be positive and negative relative to reference potential Change, change only one of positive and negative.Waveform (sin ripples, square wave, three of voltage can also suitably be set Angle ripple or sawtooth waveforms etc.).

(acoustic lens)

Lens 37 are, for example, platycelous, have plane 37p in the side of vibrating elements 35, have concave surface 37r (recesses in body surface side 37a).Therefore, as shown in Fig. 5 (b), the body of plane 37p and lens 37 is injected in axle of the sound wave along lens 37 of general parallel orientation It is above-mentioned parallel in the case that the velocity of sound in the medium (being lid 39 in present embodiment) of table side is slower than the velocity of sound in lens 37 Sound wave converges because of concave surface 37r refraction.

In addition, strictly speaking, although the shape (influence of shear wave) of medium and temperature etc. can influence the velocity of sound, at this Ignore this influence in the explanation of embodiment.Hereinafter, although enumerating the example of the velocity of sound in various media to be used as ginseng Examine, but its value is identical.

The shape and size of lens 37 can suitably be set.For example, from y-axis direction, lens 37 and concave surface 37r Shape (top plan view shape) it is mutually the same (similar), recess 37a is less than lens 37.In addition, both flat shapes can be with Coincide together.In addition, lens 37 and concave surface 37r flat shape be, for example, circle, alternatively, as long as with vibration The flat shape of element 35 is similar or coincides.From cross-wise direction, concave surface 37r can be circular arc, may not be Circular arc.In the present embodiment, concave surface 37r is substantially sphere.

Lens 37 are overall to be for example integrally formed by identical material.The material of lens 37 is by with than the velocity of sound in human body more The material of fast velocity of sound conduct acoustic waves is formed.In addition, the velocity of sound in human body can be for example with the velocity of sound in fat (about On the basis of 1450m/s) (following, identical).Specifically, such as can be for example with metal as the material of lens 37.Typically For, compared with the other materials such as resin, because of metal modulus of elasticity height etc., its velocity of sound is very fast.Metal is, for example, the aluminium (velocity of sound： 6300~6500m/s) or the stainless steel (velocity of sound：6600~6800m/s).But the material of lens 37 can also be beyond metal Other materials (for example, comparing the resin of hard).

Lens 37 (plane 37p) for example abut with vibrating elements 35.But therebetween can have bonding agent or Miscellaneous part, it is possible to have gas (air) (both can also separate).The fixed form of lens 37 and vibrating elements 35 can To take appropriate measures, such as both can be separately fixed on framework 21, can also set bonding agent therebetween.

(lid)

Form the material of lid 39 for example can propagate sound than the velocity of sound in lens 37 closer to the velocity of sound of the velocity of sound in human body Ripple.In addition, as described above, in the present embodiment, due to the velocity of sound in the material of lens 37 than the velocity of sound in human body faster, So the velocity of sound of the velocity of sound is slower than the velocity of sound in the material of lens 37 close in human body.In addition, relative to the velocity of sound in human body, lid The velocity of sound in 39 material can be with quicker, equal or slow, the e.g. slightly fast velocity of sound.

The difference of the velocity of sound and the velocity of sound in the material of lid 39 in human body can be appropriate size.For example, the difference is human body In the velocity of sound and the material of lens 37 in the velocity of sound difference less than half or less than 1/5.And/or the velocity of sound in human body and the material of lid 39 The difference of the velocity of sound in material is in below 2000m/s, below 1000m/s or below 500m/s.In addition, compared to the velocity of sound in air (about 340m/s) and the difference of the velocity of sound in human body are higher than 1000m, the difference of the velocity of sound in human body and the velocity of sound in the material of lid 39 In the case of below 500m/s, it is believed that both are sufficiently close to.

Such as when the material of lens 37 is metal, the material as the lid 39 for the important document for meeting the above-mentioned velocity of sound can example Such as use elastomer, rubber and other resins.In addition, the elastomer of present invention meaning is the elastomer (thermoplastic elastic of narrow sense Body), further, it is also possible to be in the elastomers such as phenylethylene, alkene/chain alkene, polyvinyl chloride-base, polyurethanes and amide-type It is a kind of.In addition, rubber is, for example, silicon rubber or polyurethane rubber.Using above-mentioned composition, above-mentioned elastomer or rubber can be realized With the velocity of sound of the velocity of sound same degree in human body.The matching layer of the probe of in general diagnostic ultrasound equipment or the sound of the probe The material of lens may be used as the material of lid 39.

Lid 39 is for example integrally formed its entirety by same material.But such as the surface etc. of lid 39 can also be coated with Layer, to suppress the injection of ultraviolet.In addition, lid 39 has：The inside portion 39a chimeric with the recess 37a of lens 37；Pars intermedia 39b, it is located inside portion 39a body surface side and bigger than inside portion 39a；And protruded from pars intermedia 39b towards body surface side outer Sidepiece 39c.

Because inside portion 39a is the part chimeric with recess 37a, thus its shapes and sizes and recess 37a shape and Size is corresponding.In the present embodiment, it is that sphere is corresponding with concave surface 37r, inside portion 39a outer surface is sphere.

Pars intermedia 39b for example expands simultaneously more laterally with flange 39f, the flange than inside portion 39a and outside portion 39c With substantially certain thickness.Flange 39f overlaps with the upper surface of lens 37 (around recess 37a).The shape on flange 39f Cheng Youkong 39e.The screw (not shown) engaged with flange 39f, by out of body surface side patchhole 39e and with being arranged on lens Negative thread 37e threaded connections on 37, so as to which lid 39 is fixed on lens 37.But on the basis of screw or instead of spiral shell Nail, can also use the bonding agent between lens 37 between lid 39 (inside portion 39a and/or pars intermedia 39b).Pars intermedia 39b The flat shape of (flange 39f) can use appropriate shape, be in the example in the figures circle.

Outside portion 39c (omits accompanying drawing mark with the opening formed on the surface of shell 13 (body surface side shell 15) body surface side Note) it is chimeric.Also, the surface on outside portion 39c surface and the body surface side of shell 13 is generally continuous (being generally aligned in the same plane), and Bearing surface 1a with forming physical therapy device 1 together with shell 13 and the grade of electrode 5.

Outside portion 39c shape can use appropriate shape.In the example in the figures, outside portion 39c flat shape For by the shape (Long Circle) of the cutout unit cyclotomy of a pair of electrodes 5.In addition, outside portion 39c flat shape can be circular, ellipse Circular and polygon etc..In addition, outside portion 39c surface (form bearing surface 1a face) can be it is plane or to The curved that outside slightly bloats.

Flange 39f for example expands more laterally than lens 37.Such as from body surface side make the lens 37 of ultrasonic element 3 with The opening (omission reference) being arranged on framework 21 is chimeric, and now, flange 39f is all from the opening of body surface side and framework 21 Circuit card is closed.In addition, peripheral part for being used for the opening that outside portion 39c is fitted together on body surface side shell 15 is from body surface side and flange 39f is overlapped, and flange 39f is pressed against on framework 21.That is, flange 39f contributes to relative to the mounting ultrasonic element 3 of shell 13.

(focuses of lens)

As shown in Fig. 5 (b), the focus P1 of lens 37, which is set to, makes lid 39 be located in human body (lid 39 when being abutted with body surface Outside).In addition, when the velocity of sound in the velocity of sound and human body in lid 39 is equal in theory, shown in example as shown, in lid 39 With refraction is not produced on the interface of human body.And the velocity of sound in lid 39 than human body the velocity of sound faster when, focus P1 with diagram example Son is compared away from interface；In the opposite case, focus P1 compared with example illustrated close to interface.

Focus P1 particular location can suitably be set according to physiotherapy purpose etc..As an example, focus P1 is located at body About 4mm depth under table.In this case, for example, due to thickness average out to 2mm of epidermis and corium or so, so Ultrasonic wave can be irradiated to subcutaneous fat.

Lens 37 can converge in sound wave in prescribed limit rather than by sound wave convergence on one point.For example, can be by sound Ripple pools the spherical of diameter 3mm or so.In this case, for example, reduce sound wave concentrations and can not be with physiotherapy Purpose coordinates.

In addition, in the present invention, when sound wave is converged in prescribed limit as described above, or because of accident Caused aberration and when sound wave is converged in prescribed limit, the sound wave that focus P1 can be defined as in the prescribed limit Energy reaches the volume center of highest point or prescribed limit.

In addition, for example, only judge focus P1 whether positioned at lid 39 outside in the case of, in above-mentioned prescribed limit When being integrally located at the outside of lid 39, it is not necessary to be determined as the focus P1 of a bit.Alternatively, above-mentioned prescribed limit It can also treat as focus P1.

(the basic item of electro photoluminescence)

Fig. 6 (a) is for illustrating the pulse signal to the input of a pair of electrodes 5 (alternatively from a pair of electrodes 5 to people Body provide electro photoluminescence) schematic diagram.In same figure, transverse axis represents elapsed time t；The longitudinal axis represents the strength S of pulse signal (intensity of electro photoluminescence).

Pulse signal is one kind of electric signal, and it is that signal intensity can be anti-with specified waveform relative to time process The signal changed again.By making the electric signal of this pulsation input a pair of electrodes 5, so as to assign intensity periodically to human body The electro photoluminescence of change.Pulse signal is not limited to square wave, such as can be triangular wave, sawtooth waveforms or sin ripples.

When gazing at the current potential of a pair of electrodes 5, pulse signal can make the polarity of current potential (relative between a pair of electrodes 5 In the positive and negative of reference potential) alternating inversion, electrode 5 can on the basis of current potential, only change the current potential of another electrode 5.Institute State the current potential of another electrode 5 and relative to the positive and negative variation of reference potential, can also can only make one of positive and negative and change.

The strength S of pulse signal is, for example, to flow through electric current between a pair of electrodes 5 or to applying between a pair of electrodes 5 Voltage.In other words, the electro photoluminescence that art device 1 for example provides desired electric current using constant current electrical road direction human body is applied, Constant-voltage circuit can be utilized to provide the electro photoluminescence of desired voltage to human body.For example can be in addition, applying art device 1 Human body provides the electro photoluminescence of desired electric power.

(shock wave of electro photoluminescence)

Fig. 6 (b) is the schematic diagram along the region VIb of time-axis direction enlarged drawing 6 (a).

By being compared to understand to pulsewidth Wp between Fig. 6 (a) and Fig. 6 (b), in microscopic observation, can utilize The shockwave signal higher than frequency (1/Tp) frequency of pulse signal realizes pulse signal.Pain can be reduced in this way It is known to wait bitterly and provide stronger electro photoluminescence to human body.

Although shockwave signal is a kind of pulse signal, in the present invention, as long as no special requirement, referred to as arteries and veins Shockwave signal is not implied that when rushing signal, but applies pulse signal of the art device 1 as the frequency of original purpose.

Furthermore it is possible to purpose with applying art etc. is corresponding, the frequency of appropriate setting pulse signal (and utilize shockwave signal When its frequency).Example is given one example, the frequency of pulse signal in more than 1000Hz and below 3000Hz (in so-called again and again Rate), the frequency of shockwave signal is 25kHz.Also, the frequency of pulse signal can be less than above-mentioned IF-FRE, can also compare It is high.

(adjustment of the frequency of electro photoluminescence)

The fat thickness that art device 1 is for example detected based on sensor 7 is applied, adjusts the frequency of the pulse signal exported to a pair of electrodes 5 Rate f (=1/Tp).Specifically, for example, the fat thickness of detection is thicker, the frequency f of pulse signal is higher.

For example, above-mentioned adjustment is carried out in real time.That is, the detection of fat thickness is repeated with defined cycle T c and be based on The adjustment for the frequency f that the testing result is implemented.In addition, defined cycle T c can be longer than the cycle T p of pulse signal, such as More than 0.1 second and less than 1 second.In addition, even if frequency f adjustment, the fat thickness of detection are repeated with defined cycle T c It will not be changed by previous detected value, as a result, frequency can not certainly be adjusted.

Fig. 7 (a) is schematic diagram, which show in the frequency f of above-mentioned pulse signal adjustment, fat thickness D and frequency One example of f relation.In the figure, transverse axis represents fat thickness D, and the longitudinal axis represents frequency f.

In this example embodiment, frequency f is adjusted to relative to the generally linear relations of fat thickness D.However, it is possible to as obscured Control is such, and frequency f is adjusted in a manner of the change relative to fat thickness D sexually revises in the stage.

Fig. 7 (a) concrete numerical value horizontally and vertically can suitably be set.Example is given one example, and fat thickness D is every Increase 6mm, frequency f just raises 400Hz.In addition, fat thickness D, when in the range of 0mm is less than 6mm, frequency f is 1000Hz；For fat thickness D in more than 30mm, frequency f is 3000Hz.

In addition, Fig. 7 (a) is only an example.Thus, for example, fat thickness D and frequency f can not be linear relationship. In addition, for example, frequency f change is not stepped, can be relative to fat thickness D change continuously (can be by straight Line or curve represent).

Fat thickness D and frequency f relativeness can be set by the producer for applying art device 1, one part or whole Can be by applying patient's setting.In the latter case, for example, by applying operation that patient carries out to operating portion 9 come established standardses Frequency, with the adjustment amount set in advance by producer, and based on fat thickness D change, realized by applying art device 1 to the mark The increase and decrease of quasi- frequency.

(adjustment of the intensity of electro photoluminescence)

For example, when adjusting the frequency f of pulse signal in the above described manner, it is adjoint with it, apply art device 1 and adjust pulse signal Intensity (the wave height Hp shown in Fig. 6 (a)).Specifically, for example, frequency f is higher, wave height Hp also higher (making intensity enhancing).Example Such as, it is corresponding with adjustment frequency in real time, above-mentioned adjustment is carried out in real time.That is, it is repeated with the defined cycle.Furthermore it is possible to and fat Fat thickness is corresponding, adjusts the intensity of pulse signal.

Fig. 7 (b) is schematic diagram, in being adjusted in the wave height Hp of above-mentioned pulse signal, the frequency f of pulse signal With an example of wave height Hp relations.In the figure, transverse axis represents frequency f, and the longitudinal axis represents wave height Hp.

In this example embodiment, with frequency f in generally linear relation adjustment wave height Hp.But Fig. 7 (b) with as Fig. 7 (a) that Sample frequency f change is corresponding in the form of discrete shape, and frequency f and wave height Hp relation are represented by line, but by multiple points Represent.

In addition, Fig. 7 (b) is an example.Thus, for example, frequency f and wave height Hp can not be linear relationship.This Outside, for example, frequency f change consecutive hours, wave height Hp change can be stage shape or successional.

Frequency f and wave height Hp relativeness can be set by the producer for applying art device 1, one part or all may be used With by applying patient's setting.In the latter case, for example, the operation carried out by applying patient to operating portion 9, established standardses Wave height Hp, can with advance by producer setting adjustment amount and based on frequency f change, by applying art device 1 to the standard Wave height Hp is increased and decreased.

(initial actuating of electro photoluminescence)

Such as after a pair of electrodes 5 abuts with body surface, physical therapy device 1 provides electro photoluminescence with weaker intensity to human body, this Afterwards, make the intensity of electro photoluminescence is relative to strengthen.Thus, such as reception physiotherapy person (patient etc.) psychology is reduced by the fear impacted Sense.

Fig. 7 (c) is schematic diagram, which show in the initial actuating of this electro photoluminescence, time t and pulse signal it is strong One example of (wave height Hp) relation of spending.In the figure, transverse axis represents time t, and the longitudinal axis represents wave height Hp.

In this example embodiment, before time point t0, physical therapy device 1 is not exported for providing electricity to human body to a pair of electrodes 5 The pulse signal of stimulation.Then if physical therapy device 1 detects that a pair of electrodes 5 abuts with body surface in time point t0, then to a pair Electrode 5 exports the pulse signal that wave height Hp is initial value Hp0.Then, gradually risen with the passage of time t, physical therapy device 1 Wave height Hp, after time point t1, wave height Hp is set to reach setting value Hp1.When detecting that a pair of electrodes 5 leaves body surface, return State before time point t0.

Setting value Hp1 is, for example, wave height Hp, and wave height Hp is corresponding with the frequency f that (b) of reference picture 7 illustrates and is adjusted. Therefore, in the scope shown in Fig. 7 (c), although setting value Hp1 is fixed, setting value Hp1 constantly changes according to adjustment.

Initial value Hp0 and actuation time early stage Ta (time point t0~t1 time span) can be appropriate size, can To be absolute value or value that is corresponding with setting value Hp1 etc. and changing.In addition, with this absolute value or setting value Knots modification corresponding to Hp1 etc. can be preset by the producer of physical therapy device 1, operating portion 9 can also be entered by Physical Therapist Capable operation etc. is set.

The detection that a pair of electrodes 5 contacts with body surface can suitably be carried out.For example, physical therapy device 1 can be according to a pair of electricity Whether pole 5 is powered to judge whether to contact with body surface.Now for detecting whether the signal of energization can with for human body The pulse signal of offer electro photoluminescence is identical or for detecting the special electric signal being powered.In the former case, exist Wave height Hp before time point t0 can be the appropriate value below initial value Hp0.

In addition, above-mentioned initial actuating can be applicable not only to electro photoluminescence, ultrasonic wave is equally applicable to.Such as at time point Before t0 can not output ultrasonic wave, and the intensity of ultrasonic wave is gradually risen up to setting value since time point t0.

(physiotherapy unit)

Fig. 8 is the stereogram of the structure for the physiotherapy unit 101 for representing to include physical therapy device 1.Wherein, in the figure, physical therapy device 1 is represented by double dot dash line.

Physiotherapy unit 101 is in addition to including physical therapy device 1, in addition to keeps equipment 103, and the holding equipment 103 does not make With physical therapy device 1 can be placed during physical therapy device 1.

Keep equipment 103 for example with the position for placing physical therapy device 1, physical therapy device 1 is relative to the holding shape of equipment 103 Into defined position relationship.Specifically, in the example in the figures, keep equipment 103 that there is the groove for forming and placing position 103r, physical therapy device 1 are chimeric with groove 103r.Groove 103r for example extends along vertical or along with defined angle and vertical side Extend to the direction tilted, and physical therapy device 1 is kept with upright state.

In addition, holding equipment 103 can for example play the work(of the charger to be charged to the battery 25 of physical therapy device 1 Energy.Specifically, for example, keeping equipment 103 to be electrically connected by wire (not shown) and plug with city.If in addition, by physiotherapy Device 1 is arranged in groove 103r, then the terminal (not shown) of physical therapy device 1 is with keeping the terminal (not shown) of equipment 103 to support Connect, so as to be powered from holding equipment 103 to physical therapy device 1.Also, physical therapy device 1 turns the alternating electromotive force from civil power It is changed to the direct current with appropriate voltage and is supplied to battery 25.In addition, replacing the charging carried out by this terminal, also may be used To carry out the wireless charging implemented using electric field and/or magnetic field.

As described above, on the basis of battery 25 or instead of battery, can by adapter to physical therapy device 1 supply come From the electric power of civil power.Equipment 103 is kept to play the function of this adapter.For example, connect physical therapy device 1 using wire With holding equipment 103, direct current and the confession for keeping equipment 103 by the alternating electromotive force from civil power to be converted into that there is appropriate voltage To the extremely wire.In addition, wire can be fixed relative to the one or both in physical therapy device 1 and holding equipment 103, It can assemble and disassemble.

In addition, it (is alternatively lid 39 and electrode to keep equipment 103 to have to the bearing surface 1a of physical therapy device 1 5) function of being heated and be incubated.Specifically, for example, when physical therapy device 1 is arranged in groove 103r, equipment is kept 103 have heater 105 in the opening position relative with bearing surface 1a.Also, physical therapy device 1 carries out feedback control, so that detection The detected value of the temperature sensor of bearing surface 1a temperature or the temperature of heater 105 reaches target temperature.In addition, target temperature can Preset with the producer by physical therapy device 1, can also by Physical Therapist to keep equipment 103 operating portion (not shown) Operation of progress etc. is set.

Though in addition, be not particularly illustrated, keep equipment 103 to have operating portion and display part.Operating portion is for example Including for indicating to keep the power switch of startup and the stopping of equipment 103 and/or for indicating what is carried out by heater 105 The switch of the beginning or stopping of heating and insulation.Display part for example display whether charging in, whether heat in (except for protecting The heating of temperature) and/or information in whether being incubated.

(block diagram)

Fig. 9 is the block diagram for representing the major part of the structure of signal processing system in physiotherapy unit 101.

Physical therapy device 1 has the control unit 51 for carrying out various controls.Control unit 51 is for example made up of component 23, and with Vibrating elements 35, electrode 5, sensor 7, operating portion 9 and display part 11 connect.

Control unit 51 for example with：Ultrasonic wave control unit 53, it generates and exported and is exchanged for applying to vibrating elements 35 The instruction of voltage；And drive division 55, its generate corresponding with the instruction from ultrasonic wave control unit 53 alternating voltage and by its Apply to vibrating elements 35.

In addition, control unit 51 for example with：Pulse control section 57, it generates and exports the finger for generating pulse signal Order；And drive division 59, it generates pulse signal corresponding with the instruction from pulse control section 57 and is transported to a pair Electrode 5.In addition, as the explanation such as (a) of reference picture 7~Fig. 7 (c), pulse control section 57 is based on from sensor 7 Signal changes the mode of pulse signal.

In addition, be not particularly illustrated, control unit 51 for example with：For the processing unit of output signal, the signal is used to make to show Show that portion 11 shows appropriate information；And processing unit handled etc., the processing are supported for detecting bearing surface 1a with body surface Connect.

Keep equipment 103 that for example not only there is heater 105 as described above, also have：Temperature sensor 107, it is used In detection bearing surface 1a or heater 105 temperature；For the charging part 109 to be charged to battery 25；And for above-mentioned dress Put the control unit 111 being controlled.

(example of processing step)

Figure 10 is flow chart, an example of the processing step performed which show physical therapy device 1 (control unit 51).In the figure In show by justifying 1 symbol of encirclement 1. at two, 1. symbol represents it is the part that is mutually related each other；Equally, also show in figure It is shown with two by justifying 2 symbol of encirclement 2., 2. symbol represents it is the part that is mutually related each other.

In above-mentioned flow chart, specifically, real-time adjustment (Fig. 7 (a) and Fig. 7 for electrical stimulus patternses are illustrated (b)) and the initial actuating (Fig. 7 (c)) of electro photoluminescence processing.In addition, physical therapy device 1 bearing surface 1a is abutted with body surface when Between carry out additional calculation, can have following function：Terminate physiotherapy if setting time as defined in being reached if the time, and And show the processing for this.

For example, operating portion 9 is being carried out to indicate the operation (for example, making the operation that power switch turns on) that physiotherapy starts When, start the flow.

In step ST1, control unit 51 carries out the initial setting of various parameters.For example, made with elapsed time tc, ts, ta For initial value (such as 0).The meaning in clearly above-mentioned elapsed time in the following description.

The processing of (step ST2~ST15) after step ST2 is repeated with the defined cycle.Although can suitably it set In the fixed cycle, still, the Tc and step ST12 Ta that the cycle should be than step ST2 are short.

In step ST2, control unit 51 judges whether elapsed time tc reaches cycle T c set in advance.Next, control Portion 51 processed makes processing advance to step ST3 when making affirmative determination；When making negative evaluation, processing is set to advance to step ST7。

In step ST3~ST5, the adjustment for the pulse signal that reference picture 7 (a) and Fig. 7 (b) illustrate is carried out.Specifically To say, control unit 51 is based on the signal from sensor 7, it is determined that the fat thickness D (step ST3) under current sensor 7, and And the frequency f (step ST4) of the fat thickness D setting pulse signals based on the determination, in addition, setting is corresponding with frequency f The strength S (wave height Hp) of pulse signal.

In step ST6, elapsed time tc is reset to initial value by control unit 51.On the other hand, in step ST7, control Portion 51 processed only makes elapsed time tc increase steps ST2~ST15 cycle repeatedly.Therefore, it is all whenever reaching in step ST2 Affirmative determination is carried out during phase Tc, and then performs step ST3~ST5.In addition, cycle T c length can be by the system of physical therapy device 1 The person of making sets, the operating and setting that can also be carried out by Physical Therapist to operating portion 9.

In step ST8, control unit 51 judges whether bearing surface 1a contacts with body surface.Next, control unit 51 is being made Processing is advanced to step ST9 during affirmative determination, processing is advanced to step ST11 when making negative evaluation.

In step ST9, control unit 51 only makes elapsed time ts increase steps ST2~ST15 cycle repeatedly.Equally, In step ST10, control unit 51 only makes elapsed time ta increase steps ST2~ST15 cycle repeatedly.On the other hand, in step In rapid ST11, elapsed time ta is reset to initial value by control unit 51.

Herein, elapsed time ts does not reset in step ST2~ST15.Therefore, elapsed time ts is equivalent to accumulative abutting The time that face 1a abuts with body surface.Further, since elapsed time ta increases during bearing surface 1a abuts with body surface, and Resetted when not abutting, so, the elapsed time its time point t0 equivalent to (c) since Fig. 7.

In step ST12, control unit 51 judges whether elapsed time ta reaches defined actuation time early stage Ta (Fig. 7 (c)).Also, control unit 51 is when making negative evaluation, relative to the intensity (ripple of the pulse signal set in step ST5 High Hp), it is determined that having carried out the intensity for the adjustment that reference picture 7 (c) illustrates.On the other hand, control unit 5 is when making affirmative determination, Then skip step ST13.

In step ST14, control unit 51 judges whether elapsed time ts reaches defined setting time Ts.Setting time Operation that Ts is for example carried out by Physical Therapist to operating portion 9 is set.Also, control unit 51 makes processing when making negative evaluation Advance to step ST15；When making affirmative determination, processing is set to advance to step ST16.

In step ST15, control unit 51 (that is, carried out initially for the processing for continuing the output of pulse signal For the processing for the output for starting pulse signal during step ST15).The pulse signal now exported has to be set in step ST4 Fixed frequency, and there is the intensity set in step ST5 or corrected when performing step ST13 in step ST13 strong Degree.

On the other hand, in step ST16, control unit 51 enters to exercise the processing that the output of pulse signal stops.Though in addition, It is not particularly illustrated, but should be also stopped applying alive processing to ultrasonic element 30.Therefore, the time ts of physiotherapy is carried out Setting time Ts is reached, so as to terminate physiotherapy.

As described above, in the first method of ultrasonic wave is laid particular emphasis on, physical therapy device 1 of the present embodiment is to people Body provides the ultrasonic unit of ultrasonic wave, and it includes：Generate the vibrating elements 35 of ultrasonic wave；Acoustic lens 37, it is in human body side With recess 37a, converge the ultrasonic wave direction human body side from vibrating elements 35；And lid 39, it is chimeric with recess 37a And abutted with human body.The focus P1 of the human body side of lens 37 is more located at human body side than lid 39.Lens 37 are by the first material (being metal as an example) is formed, and ultrasonic wave is in first material with than the faster velocity of sound propagation of the velocity of sound in fat. Lid 39 is made up of the second material (being elastomer as an example), ultrasonic wave in second material with above-mentioned first material The velocity of sound of the velocity of sound is propagated during the velocity of sound in material is compared closer to fat.

Thus, for example, it is possible, firstly, to the ultrasonic wave of self-excited oscillation in future element 35 is converged under body surface.As a result, example As only irradiated stronger ultrasonic wave to the specific position under body surface, so as to reduce ultrasonic wave to the specific position The risk having an impact in addition.

In addition, for example, due to 39, the lid than the velocity of sound in lens 37 closer to the velocity of sound conduct acoustic waves of the human body velocity of sound In between lens 37 and body surface, so, it is easy to for focus P1 to be set in desired opening position.Specifically, for example, working as In the case of velocity of sound identical in the velocity of sound and human body in lid 39, in theory as shown in Fig. 5 (b), on the boundary of lid 39 and human body Refraction is not produced on face.Thus, for example, refraction caused by the concave surface 37r only in lens 37, setting focus P1 (lids can be passed through The shape in the face of 39 body surface sides is arbitrary shape), so as to be easy to be designed.In addition, for example, by pressing bearing surface 1a Body surface, even if the shape at the interface of lid 39 and human body produces change, it can also reduce resulting focus P1 skew.Enter And the influence that the skew for reducing the pressure focusing P1 as caused by the massage of rolling pin formula is brought.Although with the velocity of sound in lid 39 with Carried out in case of the velocity of sound in human body is identical for example, still by making lid 39 compared with the velocity of sound in lens 37 In the velocity of sound closer to human body the velocity of sound, you can how much realize some the effect above.

In addition, for example, in the case where being not provided with lid 39, the medium of ultrasonic propagation is followed successively by lens 37, recess 37a Interior air (on the basis of atmospheric pressure) and human body.The velocity of sound in air is slower than the velocity of sound in human body, usual solid material (lid 39) velocity of sound in is faster than the velocity of sound in air.Therefore, focus P1 when being not provided with lid 39 is because relatively large curved in the 37r of concave surface Bent and body surface bending, focus P1 during than provided with lid 39 are more located at the side of lid 39.Thus, it is possible to think：Covered by setting 39, it is easy to ultrasonic wave converging to deeper position.

In addition, in the present embodiment, the velocity of sound in the material of lid 39 is faster than the velocity of sound in fat.

Therefore, compared with opposite situation, focus P1 leaves lid 39.As a result, it is possible to think to be easy to make ultrasonic wave converge Gather deeper position.Further, since the higher velocity of sound of modulus of elasticity is faster, so the material as lid 39, can be selected high-elastic The material of property modulus.As a result for example reduce because pressure caused by the massage of rolling pin formula is to lid 39 and the shape at the interface of human body Caused influence.

In addition, in the present embodiment, the material of lens 37 is, for example, metal, and the material of lid 39 is, for example, elastomer.

If using above-mentioned material, the pass of the velocity of sound between the lens 37 as described above of being content with very little, lid 39 and human body System.In addition, using elastomer and without using rubber, so lid 39 can be formed by injection molded, so as to improve production Rate.

In addition, in the second method of electro photoluminescence is laid particular emphasis on, the physical therapy device 1 of present embodiment is to provide electricity to human body The electrical stimulation device of stimulation, it has：The electrode group exposed in the bearing surface 1a abutted with body surface (is one as an example To electrode 5)；Sensor 7, it detects the fat thickness under the body surface abutted with bearing surface 1a；And control unit 51, it is used for To the paired electrode 5 output form (such as frequency) pulse signal corresponding with the fat thickness that sensor 7 detects.

The electro photoluminescence of appropriate form is provided therefore, it is possible to the difference according to fat thickness to human body.Its result is： Such as judge suitable electro photoluminescence form according to the situation at the position for carrying out physiotherapy with Physical Therapist and manually adjust pulse signal Situation compare, certain effect can be expected without the business skill depending on Physical Therapist, moreover it is possible to mitigate the negative of Physical Therapist Load.

In addition, in the present embodiment, the fat thickness that sensor 7 detects is thicker, and control unit 51 makes the frequency of pulse signal Rate is higher.

, well-known situation is, if improving the frequency of electro photoluminescence, electro photoluminescence tends to be easy to deeper under arrival body surface Position.The reasons why can enumerating, is, such as the impedance of the capacitor of cell membrane composition declines because of the rising of frequency.Therefore, it is right For electro photoluminescence, fat thickness is thicker, then its pulse mode can change to reach deeper position automatically, so that reason Suitability and simplification are realized in treatment.

In addition, in the present embodiment, the fat thickness detected according to sensor 7, control unit 51 is with defined cycle T c Repeatedly change the mode (such as frequency) of pulse signal.That is, make electro photoluminescence real-time according to the fat thickness under bearing surface 1a Change.

Therefore, detection fat thickness is so that pulse signal shape when device of the invention is with carrying out predetermined operation to operating portion 9 The device (this device is also contained in the technology of the present invention) that state changes is compared, and it can make electro photoluminescence form at any time Change be adapted to and/or be easy to follow slips of the bearing surface 1a relative to body surface.In the past and in the absence of relative to this slip And make the servo-actuated thought of the adjustment of electro photoluminescence, in addition, in existing apparatus, even if the technical ability of Physical Therapist is higher, electricity can not be made The adjustment of stimulation is servo-actuated in slip.In contrast to this, the physical therapy device 1 of present embodiment has epoch-making meaning.

In addition, in the present embodiment, physical therapy device 1 has the shell formed in strip with more than length 30cm 13.If emphasis is ultrasonic wave, shell 13 keeps vibrating elements 35, thoroughly in a manner of lid 39 is exposed from outer peripheral face Mirror 37 and lid 39；And if emphasis is electro photoluminescence, then shell 13 holding electrode 5 and sensor 7 as follows, i.e., A pair of electrodes 5 is set to be exposed at the bearing surface 1a of a part of scope as outer peripheral face center shafting, to detect the fat under bearing surface 1a Fat thickness.

In addition, in the present embodiment, the electrode group for electro photoluminescence includes a pair of strip electrodes 5, above-mentioned paired The extension side by side of the longitudinal direction of shell 13 of the strip electrode 5 along above-mentioned strip.

Therefore, rolling pin formula massage can be both carried out, can also be to a wide range of offer electro photoluminescence of human body.As a rule, Electrode 5 is made up of metal, and shell 13 is made up of resin, and the former modulus of elasticity is higher.Therefore, the electrode of strip can be utilized 5, improve rigidity of the shell 13 relative to flexural deformation.As a result can improve physical therapy device 1 massaged relative to rolling pin formula it is resistance to Long property.

In addition, in the present embodiment, from the longitudinal 2 observation of shell 13, a pair of electrodes 5 of above-mentioned strip includes respectively Along the part of side (with the face of the x-axis direction generally vertically) extension intersected with bearing surface 1a.

Thus, for example, with the device without this part laterally, (device is also contained in the technology of the present invention In) compare, from x-axis direction, electrode 5 improves the rigidity of the flexural deformation relative to y-axis direction.The result is that for example Durability can be further improved compared to the massage of rolling pin formula.Further, since the edge part of electrode 5 is not easy to abut with body surface, So electrode 5 is also smooth relative to the slip of body surface.

In addition, in the present embodiment, there is physiotherapy as the physiotherapy unit 101 of ultrasound unit or electrical stimulation unit Device 1 and the holding equipment 103 with the position (groove 103r) for being used to place physical therapy device 1.Physical therapy device 1 has to control The battery 25 of portion 51 (vibrating elements 35 and electrode 5) power supply.Keep equipment 103 that there is the charging part to be charged to battery 25 109 and the heater 105 that is heated to bearing surface 1a (lid 39 and electrode 5).

Thus, for example during being charged to battery 25, bearing surface 1a temperature can be made higher than temperature.Its result It is, such as when making bearing surface 1a be abutted with body surface, it is possible to reduce the relatively low bearing surface 1a of temperature makes person under physical therapy feel not Comfortable situation.

In addition, in embodiment of above, physical therapy device 1 is an example of ultrasonic unit, and metal is the first material An example, elastomer is an example of the second material, and physiotherapy unit 101 is an example of ultrasound unit, groove 103r is an example for placing position.

The technology of the present invention is not limited to embodiment of above, additionally it is possible to implements in a variety of ways.

For example, ultrasonic unit (physical therapy device) can not have the structure for being used for that electro photoluminescence to be provided to body surface, can also Using the structure for beling not applied to the massage of rolling pin formula.

Acoustic lens can be the concavees lens beyond plano-concave lens, such as can be double concave lens or concave-convex lens.But It is, according to the structure of embodiment, then with advantages below：Easily make flat piezoelectric element close to the flat of acoustic lens Face abuts with the plane.In addition, acoustic lens can use segmenting structure as Fresnel Lenses, can be relative to one Individual vibrating elements arranges smaller multiple acoustic lens.In addition, acoustic lens can not have along the x-axis direction with z-axis direction both sides The effect of sound wave is converged, can be formed in a manner of cylindrical lens.In addition, the flat shape of acoustic lens (recess) is (from y-axis side To the shape of observation) be not limited to circle, for example, from surface observation can be rectangle.

Detection fat thickness sensor is not limited to optical sensor.For example, it may be ultrasonic sensor. Ultrasonic sensor receives the reflected signal and generation figure of the echo-signal of transmission for example as diagnostic ultrasound equipment Picture, and according to image analysis come determine muscle and fat border, according to the transmission of echo-signal and based on until receive with Time and the velocity of sound pre-entered untill reflected signal corresponding to the border of determination, calculate fat thickness.

In embodiments, the fat that the frequency (1/Tp) of pulse signal and intensity (wave height Hp) detect according to sensor Thickness and accordingly change.But it is also possible to only make frequency or only change intensity.Moreover, on this basis or replace in This, for example, can make pulsewidth Wp (being alternatively dutycycle) and/or waveform (square wave, triangular wave, sawtooth waveforms or The shapes such as sin ripples) change.
